LIGHTER FOR GAS STOVES.

This invention relates to improvements in oven lighers for gas stoves, and consists in the novel construction hereinafter disclosed.

An object of the invention is to provide an improved device for automatically igniting the gas issuing from a burnerv remote from the flash pilot light of a gas stove, said device being so constructed as that the gas issuing from thel burner to be ignited is mixed with air and conducted through a tube to a point adjacent to a flame issuing y from the flash pilot light.

Another object', of the invention is'to co ordinate the orifice through which the gas issues from the burner to be ignited to the tube so that, when the gas is ignited, the flame from said ignition point will be out of Contact with the metal part of a tube through which the gas mixed with air is conducted to a point where it is ignited by a flame issuing from the flash pilot light.

Another object of the invention is to provide a simplified and improved construction comprising a tube having its ends opening toward and spaced from a gas burner anda flash pilot light respectively in order that gas issuing from thel burner will pass through said tube with a proper admixture of air forming a combustible gas that will be readily ignited when the flame from the flash pilot light is Hashed adjacent to the end of the tube, but out of contact therewith, whereby the flame is conducted to a remote point to ignite the gas issuing from the re motely disposed burner.

Other objects of the invention will appear from the following detailed description thereof taken in connection with the accompanying drawing, in which Fig. 1 is a plan view of a gas stove showing a cluster of burners and with a portion of an oven burner disposed remotely therefrom.

Fig. 2 is a'detail view of the ignition orifice leading from-the oven burner showing the relation of the orifice to the end of the ame-conductin'gtube.

Fig. 3 is a. detail View showing the relative position of theV opposite end of said flame-conducting tube -in relation to the flame issuing from the flash pilot light. v

In the embodiment of the invention illustrated in the drawing a gas stove of usual construction is illustrated. This comprises a foid 2 through supplyv conduits roup of burners l connected into a mani 3. A flash pilot light of familiar construction is associated with the burners 1, being associated in the group Yof burners in such a position that a flame is flashed therefrom across the surface of the burners for igniting vthe same. The said flash pilot light includes a burner tip'li that is supplied with gas through a conduit 5 connected into the manifold 2, the flow-of lgas through the conduit 5 being controlled by a valve 6 of familiar construction. It will be understood that the valve 6 is normally in adjustment to admit only a sufficient amount of gas to'pass through the burner tip to provide-apilot light and that, when it is desired to -create a flash to ignite gas issuing from any of the group of burners 1, the Valve is opened to a greater extent so that flames flash from the burner tip through the several orifices therein and outwardly through openings 7 in the casing 8 that encloses the pilot light.

An oven burner 9 that is provided with a plurality of the usual ygas issuing orifices 10 is located at a point remote from the lgroup of burners l, said burner being supplied from the main manifold 2 through a valve-controlled conduit 11. The burner, 9 is provided also with an orifice 12 through the side wall thereof, which orifice 12 is po*- sitioned so that, when the gas issuing therefrom is ignited, a flame. is created which burns with substantially complete combustion and out of contact with a flame-conducting tube.

The flame-conducting tube 13 extends from a point spaced from the burner 9 to a point spaced from the pilot light,.said tube 13 being supported in any convenient manner by the stove construction-and, in the embodiment illustrated, by a strap 14 connected with a portion of the burner 9 and with the mix with a quantity of air forming an admixture of a highly combustible character,

which enters the tube 13 and is conducted to a pointvwithin the vicinity of one of the flash llames issuing from the pilot light burner. The spacing of the end. of the tube v13-from the orifice 12 is such also that,

when the gas is ignited that issues from the orifice 12, a iame is produced which burns in contact with air and therefore provides for complete combustion thereof out of coni tact with the end of the tube. By arrangvus ing the orifice 12 at a position below the axis of the tube 13, when the flame burns, it will burn with a point substantially coaxial with the tube 13, but out of contact If the construction was such with said tube. that the flame issuing from the orifice 12 came in contact with the tube 13 there would `form a deposit of carbon and there would the'ash pilot lig'ht nor from the burner,

contacts directly with the metal of the tube.

In operation, the yalve (i of the flash pilot.

light burner is opened, and the gas supply to the. burner '9 is opened. .r'lhergas issuingv from the'oriice 12 enters the tube 3 together with an admixture of air and is conducted to the opposite end Where it is ignited from the heat created by the flash flame traversing above the end of said tube. When the iame Y Hm, exact construction shown and described,

' ignites, it fis conducted backwardly through the tube igniting the gas issuing from the orifice 12 from which it is propagated around the burnerv .to each ofthe orices of the burner being ignited serially.

l While the'invention has been shown as em.- u

bodied in a gas range or stove comprising burners of familiar construction and as applicable for lighting an ovenburner, it will be understood that the invention may be varied within equivalent limitsl Without departure from the nature and principle thereof. Accordingly, I do not restrict myself t0 the pilot` light andv provided with a gas outlet, and a tubev supported between the burner and the pilot light and having an open end below the plane of the`fla1ne issuing from the pilot light and an open end arranged to receive and conduct gas issuing from the burner toward the pilot light.

3. A device .of the character described comprising a pilot light, a gas burner having a gas outlet orifice through a lateral wall thereof, and a tube having an open end, the axisof which is above said gas outlet, and adapted to receive gas fromsaid outlet and spaced therefrom, said tube extending to`- ward and xterminating at a distance laterally from said pilot light. fr ff" Y 4. A device of theharacterl described comprising a pilot light having a flash flame opening, a burner having a gas outlet, and

fatube supported between said burner and saidiilot light and having open ends spaced from both. l

5. A device of the character described comprising a flash pilot light, a gas burner having gas outlets through the -wall thereof, and agas outlet opening in another direction, in combination with a tube having an open end adjacent to and spaced from said last-named outlet and havingits opposite end opening toward and spaced from said pilot light.

6. A device of the character described vcomprising a flash pilot light; a burner, and

a tube arranged to confine' gas, said tube' I being located between` said burner and said pilot light and having open ends opening toward and -spaced from said pilot light and burner respectively.
